- Wash your face or take a shower.
- Dry off, and rub in some moisturizer (it won't affect your visual exam).
- Take a good look in the mirror as you answer the test's questions. And try not to cheat! That means fessing up to things you'd rather ignore and not pulling or tugging on your skin to influence what you see. No one is watching you, and you won't be graded, so be true to yourself.
Younger than 30? You don't have enough visible aging to measure yet. Older than 70? The gap between your skin's RealAge and your calendar age won't be significant.
